The range of machines that can run on renewable fuels is increasing. First of all it's cars with ethanol (E85) and biogas can be used. There is also a certain range of electric cars and hybrid vehicles.
For those who have significantly reduced emissions of carbon dioxide per kilometer.
Gasoline
Gasoline is still the fuel of choice in the world. 95-octane is sold 95 percent of oil and five percent ethanol. Parts of ethanol are now five percent of the EU directive on fuel quality, but it changed the rules. From January 2011 the possibility of increasing this percentage to 10 percent.
Diesel
If you choose a diesel car fuel consumption and passenger carbon emissions by about 20 percent lower than a petrol engine of similar size and performance compared to diesel due to the increased energy efficiency. During the combustion of one liter of diesel is 2.48 kg of carbon dioxide from fossil fuels. Considering the site (such as air pollution caused by the refining, distribution, etc.) emissions throughout the life cycle of 2.98 kg of fuel are taken. Compared to a diesel vehicle with petrol engine caused an increase in emissions a bit "of NOx in the first place - acidifies the soil and water - and the particles that are harmful to the respiratory and cardiovascular systems.
Most new cars have diesel particulate filters (Environment 2005PM), which reduces these problems.
Ethanol (E85)
E85 (15 percent ethanol to gasoline, 25 percent mixed in winter) is a fuel made primarily from renewable resources such as sugarcane and corn. Ethanol has a lower energy content than gasoline. Consumption per thousand is more than about 35 percent compared to gasoline. From the perspective of the life cycle of carbon 55 percent less than gasoline. Generated when one considers the emission of carbon dioxide in the production and sale of ethanol and gasoline.
Cars can run on E85 as a flexi-fuel car, because it can run on any mixture of gasoline and E85. Evaluation of the Agency that the percentage of E85 ethanol in the vehicle was refueled in 2009 was about 60 percent. With this level of E85 ethanol fueling vehicles issued by about 20 percent less carbon dioxide than the average petrol car again. Emissions of other substances which are environment and health is about the same for gasoline vehicles.
The number of gas stations with E85 is increasing rapidly throughout the country and the beginning of September 2010 there were about 1700 pieces.
Vehicle
Fuel is composed primarily of methane. It can be extended (biogas produced from organic materials such as sewage sludge, manure and waste) and fossil fuels (natural gas).
Biogas cleaned, released essentially no emissions of fossil fuels, but small amounts of methane gas emissions in production. Although biogas vehicles and affect the climate, but the emissions are 80 to 90 percent less than gasoline. Natural gas reduces emissions of carbon dioxide than diesel than gasoline, which is about 20 percent. Emissions of other substances which are environment and health is about the same for gasoline vehicles.
Many models and run a shorter distance with gasoline before lighting the gas engine. The tank can sometimes be low (15 liters), while other models have larger tank, and you can make a greater distance than gasoline.
Hybrid electric cars
In hybrid cars combine a conventional internal combustion engine with one or more electric motors and a battery to store energy from the engine and braking. In this way, fuel consumption is lower. Since the combustion engine is stopped automatically when you stop at a red light, for example, it is idle. Hybrid electric cars have their greatest advantage in the dense urban traffic, where the number of starts and stops are great, but operation of the road, consumption is relatively low, given that hybrid vehicles are usually equipped with relatively small internal combustion engines.
